I agree with Dante. Uchronia always felt like a more considered engine-builder, less prone to lucky draws than GTR. Mottainai, on the other hand, is the shortest, wildest of the three siblings. If I want a wild, semi random game, I'd choose Mottainai; if I want a sensible engine-builder, it's Uchronia.

Two improvements - I replaced my resource cards with five colours of cubes drawn from a bag, which takes up much less space, is faster and less troublesome to shuffle. And I clipped the corners of my building cards.

Forgot to mention the corner clipping, I did that as well. Absolutely love your resource cube idea. Will definitely be considering that!
